A smart BMS (battery management system) monitors and manages lithium battery packs to ensure safety, efficiency, and longevity. The JK-B2A24S20P smart BMS provides active balancing, real-time monitoring via Bluetooth, and robust protection features, making it essential for high-performance applications like EVs and solar storage.
The JK-B2A24S20P is optimized for lithium battery packs (7S to 24S). While primarily designed for lithium-ion or LiFePO4 batteries, compatibility with other chemistries depends on voltage and configuration. Always verify specifications before use.
Active balancing redistributes energy between cells to maintain uniform voltage, unlike passive balancing, which dissipates excess energy as heat. This smart BMS’s 2A active equalization enhances efficiency, extends battery life, and improves overall performance.
Yes, the built-in Bluetooth connects to an intuitive Android/iOS app, allowing users to monitor voltage, SoC, and temperature in real time. This feature simplifies battery management and provides actionable insights for optimizing lithium battery systems.
